M135i vs M135i LCi

[M2withACC]

Hey folks,

I just picked a fully loaded 2014 M135i with 9300km on it. I am just very curious what's the difference between the LCi models? I think 6hp bump and 0.1 torque bump. Is there any hardware mechanical difference? I am sure BMW updated the ECU and most likely a few minor tweaks in the ZF 8 speed gear box? Is possible to get the latest software to behave like the latest M135i? Or Is there any 3rd party tuning company can do this?

( it pretty much drove the same as my previous 2015 M235i 8 speed )

Many thanks!
